Last night, we went out to a local restaurant and tried their all-you-can eat lobster Wednesday for $49.99. It comes with a cup of New England Clam Chowder, about 10 roasted red potatoes, small amount of Ziti in an alfredo sauce, small piece of corn-on-the-cob, and homemade garlic rolls. My wife surprised me as she eats so much like a bird that a 1/2 whopper JR filled her up earlier in the day, by eating 3 whole lobsters. My mom had the same, and I ended up at 4. It was the first time at this restaurant and the service team was excellent as they kept the drinks filled, cleaned out the shell bowls quickly, and was ready to bring out the next one just as we finished up with the previous one. The only other AYCE lobster that I know of is in the Orlando area where it's a buffet and costs around $70/pp.
They also have an AYCE King Crab on Tuesdays for the same price that we decided we must try.
